LAMP-'EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 706,572, dated August 12 1902.

Application filed March 5, 1902. Serial Nof9 3l840. (N0 model.)

To all whom, it may concern:

Be it known that I, LEROY DLLAWRENOE, a citizen of the United States, residing atParsons, in the county of Labette and State, of

Kansas, have invented certain new and useful Improvements in Lamp-Extinguishers; and I:

do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Thisinvention relates to new and useful improvements in lamp-extinguishers; and it con-- sists in the provision of an attachment to a lamp-burner which is adapted to extinguish the flame from the wick and also to scrape off the burned or charred end of the wick; and it consists in the provision of a spring-actuated angle-plate which is adapted to be actuated by means of a tubular key, whereby the plate may be thrown over the top of thewick-tube,

said plate being adapted to return to its normal position by means of the spring secured thereto.

The invention consists, further, in connection with the spring-actuated extinguishingplate, of a perforated slide, rwhich is carried by the plate and adapted to close over the. apertures in the perforated top of the burner,

in which said plate has a swingingmotion. Theinvention consists, further, in various details of construction, which will be hereinafter fully described and then specifically defined in the appended claim, and is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing my improved light-extinguishing attachment Fig. 2 is a central vertical section through the burner. Fig. 3 is a detail view of the swinging flame-extinguishingplate and wick-turner shaft. 'Fig. l'is a detail view of the hollow shaft which actuates theswinging flame-e20- wheels D, which turn in said wick-tube, as is common in burners. r

E designates a flame-extinguishing plate which isbent at right angles adjacent to its freeend'and is provided with ears F at the opposite longitudinal ends of said plate,which ends arebent, preferably, at right angles to the-length of said plate, and said ends are adapted to be journaled on thewick-turning shaft. A spring H is fastened at one end to said plate and is bent, preferably, as shown, has its free end adapted to yieldingly bear against the inner circumferenceof the flange about the burner when said plate is thrown into a position so that the ,angled portion thereof will project over the top of the wicktube. This spring is provided to normally hold said plate at its farthest outward throw. In order to strengthen and make said plate more rigid, I form ribs H across the plate, and in the-drawings I have shown these ribs as crossing each other.

i The tubular key K, which is hollow, is fitted over the wick-turning shaft and has a motion independent of said shaft and is provided with a turning-wheel K at one end. The inner end of said tubular key is cut away, as at M, and is provided with a notched portion M, which as said key is rotated in one direction is adapted to engage a notch. Nin one of the apertures of an ear of said plate, whereby said plate may betilted for the purpose of extinguishing the flame from the wick by said angled portion of the plate closing over the upper end of the wick tube, which will smother theflame, and at the same time the charredend of the wick may be scraped 01f.

The'perforated top Q of the burner has a slot Q formed therein, whereby said angled flame-extinguishing plate may have a swinging motiom' Inorder to cause said opening tobe covered, so as to allow an even supply of air to be fed to the flame, I provide a perforated plate R, which is longitudinally slotted, as at R, and fitted over the angled plate and is adapted toslide on the-uppersurface of the perforated plate of the burner, as will be readily understood.

The utility of my invention will be readily understood and owing to the simplicity of its construction may be easily attached to all the ordinary lamp-burners with a slight expense,

and the operation of the device is effected by merely turning the wheel at the end. of the tubular'key, which will cause the angled plate to smother the flame and to snuff or scrape off the charred end of the wick.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a burner having a perforated top, a wick-tube and wick-operating shaft, a flame-extinguishing plate having ears which are perforated and journaled on said shaft, said plate having a play in an elongated aperture in said perforated top of the burner,

a perforated sliding plate having an elongated I 5 slot to receive said extinguishing-plate, and adapted to slide upon the perforated top of the burner, and a tubular key for throwing the extinguishing-plate over the Wick-tube, and asprin g for returning said extinguishingplate to its normal position, as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

LEROY D. LAWRENCE.
